This is the problem, I have managed to get the 3d plug-in to work on my site using IE. When I use Netscape I get the message "click here to get plug-in", I click it, then I get a new page that tells me "NOT FOUND".
I have posted the code on here to see if anyone can tell me what I am doing wrong.

My english is bad but I try to help you.
First of all, are you sure you have well downloaded the pluggin.
To be sure, open in the menubar "help" and chose "about pluggins": you must see all installed pluggin for your netscape.

Ok, then take a look at your HTML code again. See the PLUGINSPAGE=... line? At least for me plugin.blender.nl doesn't work (no wonder...).

A workaround could be to link to another page offering the plugin, but make sure you don't violate any license (the binary only plugins are still NaN property, and I have not seen an open source build of the plugins). I asked questions about this a while back, you should be able to find the threads on this forum.

Correct me if I'm wrong, especially when it comes to the license stuff and a free plugin build. I'd love to hear some good news about that myself

I just put the plugins up on my website again for installation because the pages on the old blender site aren't setup correctly for the installl... they just have the info.. so I "borrowed" some of the info and put it up... I am still having problems with a corrupt JAR file for the netscape plugin... there isn't an Auto-Install for netscape.. the user has to click a button. And its even more manual when the user is using linux. http://www.pablosbrain.com/ just click on blender. Hopefully I'll get the netscape one working later this coming week. As I understand the licenses.. I can distribute the plugin from my website being a Publisher Owner. Thats my understanding, as the plugins are freely available to be downloaded from blender.org... but I could very well be wrong.
